A Proxy-Caching Prefix Assignment Algorithm Based on P2P Cooperation in the Media Streaming System
Consider the lack of cache and serve time-delay in the media streaming system, a Proxy-Caching Scheduler based on P2P Cooperation (PCSPC) is raised. First according to the principle of more popularly data assigned more cache, we distribute corresponding cache to every media files prefix by its popularity. Then we sort prefix sequence in ascending order and proxy sequence in descending order by transmission cost, this method can reduce transmission cost effectively, which is proved by mathematical method. All above make PCSPC give attention to cache efficiency and transmission cost. Simulations demonstrate the validity of the designed approach.
